With the 5.10 versionthe problem is reduced but always present, if you try to draw these three rectanglesRectangle(20,20,30,30);Rectangle(30,20,40,30);

Rectangle(20,31,30,41);you will notice that the common side of the first two rectangles (at the 30 position), appear more marked thanright side of the third rectangle (at the 30 position)all sides that the rectangles have in common seem designed more markedin my invoice report is not goodI wish that all the lines of the rectangles had the same thickness
